Description

[Technical Field]

[0001] The present invention relates to a hanging wrist roller device that allows a user to rotate a grip bar while suspended in the air to perform wrist roller exercises. [Background technology]

[0002] A hanging wrist roller device is known as one of the exercises for strengthening the forearm muscles. Figure 1 shows the hanging wrist roller device invented by the present inventor and disclosed in Korean Patent Publication No. 10-2018-0010415.

[0003] Referring to FIG. 1 , a known hanging wrist roller device includes a grip bar 1 with a weight 3 suspended by a string and a hanger piece 5 that suspends the grip bar 1 from an upper support (not shown) using a band-shaped strap 8a or rope 8b. The hanger piece 5 is made of metal and includes an upper part 5a to which the band-shaped strap 8a or rope 8b is fixed, and lower parts 5b on both sides with loops 6 to which the grip bar 1 is hooked. The loops 6 of the lower parts 5b are hooked into the loop grooves 2 of the grip bar 1. The band-shaped strap 8a is directly fixed to the hanger piece 5, and the rope 8b can be connected to the hanger piece 5 via hooks 9. The hanging wrist roller device is a device for performing wrist roller exercises by holding the grip bar with both arms extended forward while the grip bar is suspended in the air and rotating the grip bar alternately with one hand. The hanging wrist roller device is advantageous for training the forearm muscles of both arms in a balanced manner.

[0004] However, known hanging wrist roller devices have the following drawbacks. First, it is difficult to adjust the height of the grip bar. It is generally known that hanging wrist roller devices are effective when exercised with arms extended parallel to one another. However, known hanging wrist roller devices are initially set at a fixed height, making it difficult for exercisers to adjust the height of the grip bar to fit their body. Second, because the loops of the hanger pieces are partially open to allow the insertion of the grip bar, care must be taken to prevent the grip bar from coming loose during exercise. Third, as the grip bar rotates, friction occurs between the metal loops of the hanger pieces and the grip bar, disrupting exercise balance and generating noise and wear.

[0015] Hereinafter, detailed descriptions of the present invention will be described with reference to the accompanying drawings. In describing the present invention, detailed descriptions of known functions will be omitted if they are obvious to those skilled in the art and are deemed to unnecessarily obscure the gist of the present invention.

[0016] FIG. 2 is a front view of a hanging wrist roller device according to an embodiment of the present invention, and FIG. 3 is a partially enlarged perspective view of the hanging wrist roller device according to the present invention, with FIG. 3(a) and FIG. 3(b) showing opposite directions.

[0017] 2 and 3, the hanging wrist roller device according to an embodiment of the present invention includes a grip bar 100, a height adjustment plate 200, an upper rope 300 for hanging the grip bar 100 from a support base 10 arranged above, and a lower rope 400 for hanging a weight 500 from the grip bar 100.

[0018] The grip bar 100 includes a center portion 110, left and right handles 120 provided on both sides of the center portion 110, and sheaves 150 located between the center portion 110 and the left and right handles 120.

[0019] The center part 110 is located in the middle of the grip bar 100, and is a part around which the lower rope 400 is wound, and may be formed in a cylindrical shape.

[0020] On both sides of the center part 110, lower rope fixing parts 112 are formed to which both end parts of the lower rope 400 are fixed.

[0021] The handles 120 are the portions with which the user holds the grip bar 100 and are disposed on both sides of the center portion 110. The handles 120 are configured to rotate together with the center portion 110. The left and right handles 120 may be formed integrally with the center portion 110 or may be connected to it as one unit.

[0022] Sheaves 150 are provided on both sides of the center portion 110 between the left and right handles 120. The sheaves 150 include grooves 152 formed in the circumferential direction of the grip bar 100. The sheaves 150 are portions that support loop portions 350 formed at the lower part of the upper rope 300, and the loop portions 350 are hooked onto the grooves 152 of the sheaves 150.

[0023] The upper rope 300 connects the upper support base 10 and the grip bar 100, and functions to suspend the grip bar 100 in the air. Although the support base 10 is shown in a rod shape in FIG. 2, it is not limited thereto and may have various other shapes. For example, it may be a ring suspended from a structure to which a string can be fixed. If the support base 10 is rod-shaped, it may be connected by forming a knot.

[0024] The upper rope 300 includes first and second upper rope sections 310, 320 that branch off from the support 10 and extend downward. The upper rope 300 may be formed as a single rope. The central section of the upper rope 300 is connected to the support 10 by forming a knot 302, and both side sections extend downward while forming the first and second upper rope sections 310, 320.

[0025] The loop portions 350 are formed at the bottom of both sides of the upper rope 300. The loop portions 350 are formed in such a way that both side portions of the upper rope 300, i.e., the first and second upper rope portions 310 and 320, extend downward through the height adjustment plate 200, change direction through the groove 152 of the sheave 150, extend upward, and are fixed to the height adjustment plate 200.

[0026] The lower rope 400 has a function of hanging the weight 500 on the grip bar 100. The lower rope 400 is connected to the weight 500 at the lower end thereof, and includes first and second lower rope portions 410 and 420 that are branched and extended upward.

[0027] The lower rope 400 may be formed as a single rope. The lower rope 400 passes through a loop formed at the upper end of the weight 500 and extends upward, and the extending portions on one side and the other side become the first and second lower rope portions 410 and 420.

[0028] The upper ends of both sides of the lower rope 400 are fixed to lower rope fixing parts 112 formed on both sides of the center part 110 of the grip bar 100. The lower rope fixing parts 112 may be formed as holes located on both sides of the center part 110. The rope fixing parts will be described later.

[0029] When the upper ends of the first and second lower rope portions 410, 420 are fixed to the center portion 110 of the grip bar 100, the weight of the sinker 500 is easily positioned on the center line of the lower rope 400.

[0030] The lower rope 400 forms an inverted triangle between the weight 500 and the grip bar 100. Therefore, by holding the handle 120 and rotating the grip bar 100 in one direction, the first and second lower rope sections 410, 420 are wound spirally around the center section 110 toward the center, lifting the weight 500. By rotating the handle 120 in the opposite direction and rotating the grip bar 100 in the other direction, the weight 500 is lowered. By repeating this action, the forearm muscles are strengthened.

[0031] A height adjustment plate 200 is located above the grip bar 100. An upper rope 300 passes through the height adjustment plate 200 and is connected to the grip bar 100. The first and second upper rope portions 310, 320 pass through the height adjustment plate 200, extend downward, and are hung on a sheave 150, then change direction to form a loop portion 350, which is then fixed to the height adjustment plate 200.

[0032] Because both ends of the upper rope 300, i.e., the ends of the first and second upper rope portions 310 and 320, are fixed to the height adjustable plate 200, adjusting the position of the height adjustable plate 200 up or down adjusts the size of the loop portion 350. Because the loop portion 350 is an extension of the upper rope 300 that overlaps, for example, as the size of the loop portion 350 increases, the height of the upper rope 300 decreases. Because the sheaves 150 of the grip bar 100 are hooked onto the loop portions 350 on both sides of the upper rope 300, adjusting the height of the height adjustable plate 200 also adjusts the height of the grip bar 100. Therefore, the height of the grip bar 100 can be adjusted to a height suitable for hanging wrist roller exercise by moving the height adjustable plate 200 upward or downward.

[0033] On both sides of the height adjustment plate 200, rope connecting portions 250 are formed through which the first and second upper rope portions 310, 320 pass and to which the ends are fixed.

[0034] The rope connection part 250 includes at least two through holes 252, 254 extending downward through the first and second upper rope parts 310, 320, and a fixing hole 256 for fixing the first and second upper rope parts. The through holes 252, 254 and the fixing hole 256 are functionally separate and may have the same shape.

[0035] According to an embodiment of the present invention, the distance between the rope connecting portions 250 formed on both sides of the height adjusting plate 200 corresponds to the distance between the two sheaves 150 on both sides of the grip bar 100 .

[0036] The height adjustment plate 200 allows the positions where the loop portions 350 on both sides are formed to be spaced apart by an amount corresponding to the distance between them and the sheave 150. The first and second upper rope portions 310, 320 that pass through the height adjustment plate 200 are extended almost vertically downward to be hung on the sheave 150 and then extended almost vertically upward to form the loop portions 350. Because the left and right loop portions 350 extend almost parallel to the sheave groove 152, even if the grip bar 100 swings as the user turns the grip bar 100 due to the wrist roller, the loop portions 350 of the grip bar 100 are stably supported without coming off the sheave groove 152.

[0037] The rope connection portion 250 includes at least two through holes 252, 254. The two through holes 252, 254 are arranged one above the other. A fixing hole 256 is arranged adjacent to the through holes 252, 254.

[0038] The first and second upper rope portions 310, 320 pass through two through holes 252, 254 arranged above and below in a zigzag pattern and extend downward, are hung on the groove 152 of the sheave 150, extend upward, and then pass through the fixing hole 256.

[0039] The first and second upper rope portions 310, 320 that have passed through the fixing holes 256 are fixed by a method such as a knot. A fastener may be used instead of a knot.

[0040] FIG. 4 is a partially exploded perspective view of the grip bar of the hanging wrist roller device according to the present invention, and FIG. 5 is a cross-sectional view of the grip bar shown in FIG.

[0041] According to one embodiment of the present invention, the grip bar 100 includes a grip bar body 140 including a center portion 110 and two handles 120, and a sheave 150, which are assembled together.

[0042] The grip bar body 140 includes a center portion 110 and handles 120 on both sides. The center portion 110 and the handles 120 on both sides are joined together and integrated so as to rotate together.

[0043] The center portion 110 includes a rod-shaped center body 114 and first connecting portions 115 formed on both sides of the center body 114 .

[0044] The center body 114 is the portion of the grip bar 100 around which the lower rope 400 is wound. Hole-shaped lower rope fixing portions 112 are formed on both sides of the center body 114 in a direction intersecting the central axis in the longitudinal direction. The lower rope fixing portions 112 are arranged symmetrically in the center portion 110. The hole forming the lower rope fixing portion 112 penetrates the center body 114 in the diameter direction and has a stepped surface inside. Therefore, when the end of the lower rope 400 is inserted through one side opening of the lower rope fixing portion 112, a knot is formed at the end, and the end is pulled, the end of the lower rope 400 is fixed to the lower rope fixing portion 112.

[0045] The first coupling portion 115 may be formed as a protrusion extending in the longitudinal direction. The first coupling portion 115 has a first coupling hole 116 for a fastening member 130. The handle 120 is coupled to the first coupling portion 115.

[0046] The handle 120 may be rod-shaped and have grip grooves formed on the outer periphery for easy holding. The handle 120 may be hollow. Caps 129 may be attached to the openings at both ends in the longitudinal direction to prevent the handle 120 from being hollow.

[0047] A second connecting portion 125 is formed at the end of the handle 120 facing the center portion 110, and is connected to the first connecting portion 115. The second connecting portion 125 is formed in the form of an insertion hole into which the first connecting portion 115 is inserted. The first connecting portion 115 and the second connecting portion 125 have complementary shapes.

[0048] The second coupling portion 125 has a second coupling hole 126 formed therein, which is aligned with the first coupling hole 116 of the first coupling portion 115 .

[0049] The center portion 110 and the handle 120 are fixed by inserting and assembling the first and second coupling portions 115 and 125, and then coupling the fastening member 130 to the corresponding first coupling hole 116 through the second coupling hole 126. The fastening member may be a pin, a bolt, or the like. When a bolt is used as the fastening member, the second coupling hole 126 may be formed in a shape that does not completely penetrate the second coupling portion 125. Therefore, the lower portion 126a of the second coupling hole 126 may be formed within the second coupling portion 125.

[0050] According to an embodiment of the present invention, the fastening member 130 may be a bolt having a thread formed on its outer periphery and may be threadedly coupled to only the first coupling hole 116. That is, the second coupling hole 126 of the second coupling portion 125 located on the outer side of the first coupling portion 115 and the second coupling portion 125 may be an insertion hole without a thread, and the first coupling hole 116 of the first coupling portion 115 located on the inner side may be a nut hole having a thread formed on its inner periphery. When the fastening member 130 formed as a bolt is inserted through the second coupling hole 126 and screwed into the first coupling hole 116, the first coupling portion 115 is pulled toward the inner periphery of the second coupling portion 125, thereby tightening the bolt. As a result, the second coupling portion 125 undergoes micro-compression deformation, thereby fixing the first coupling portion 115 and the second coupling portion 125 together. Since the center part 110 and the handle 120 are firmly fixed together, there is no play, and loosening of the bolt is prevented by the minute compressive deformation of the second connecting part 125. This principle is similar to the fixing principle that occurs when assembling a screw through a washer.

[0051] Sheaves 150 are coupled to both sides of the center portion 110 of the grip bar body 140. According to an embodiment of the present invention, the sheaves 150 are formed as bearing type sheaves. The bearing sheaves 150 are inserted into the first coupling portion 115 through the mounting hole 151, and the bearing sheaves 150 have grooves 152 formed in the circumferential direction on their outer circumferential surfaces.

[0052] The bearing sheave 150 may have various configurations. For example, it may have a groove 152 formed on the outer ring, with the outer ring separated so that the outer ring and inner ring rotate independently. Alternatively, it may have a bearing mounted on the inner surface of the bearing sheave mounted to the first coupling part 115, or a bearing surface formed on the inner surface. A bearing is a component that allows relative rotation between the shaft on which it is mounted and the part it supports, and in this specification, the bearing sheave 150 rotates relative to the grip bar body 140.

[0053] The bearing sheave 150 prevents the rotation of the grip bar body 140 from being transmitted to the loop portion 350 of the upper rope 300, so that the exerciser can hold the handle 120 and rotate the grip bar body 140 more stably.

[0054] 6 is a cross-sectional view showing another embodiment of the grip bar of the hanging wrist roller device according to the present invention. Referring to FIG. 6, the center portion 110, the handles 120 on both sides, and the sheave 150 of the grip bar 100 may be integrally formed.

[0055] The grip bar body 140 is formed in a rod shape, with handles 120 extending from both sides of a center portion 110 located in the middle. The grip bar body 140 may be hollow, and caps 129 may be attached to the openings at both ends in the longitudinal direction to prevent the handles 120 from becoming hollow.

[0056] A sheave 150 is formed between the center portion 110 and both side handles 120. The sheave 150 is formed integrally with the grip bar body 140.

[0057] The sheave 150 protrudes in the radial direction of the grip bar body 140 and has a central portion recessed in the circumferential direction to form a groove 152 .

[0058] Since the sheave 150 is formed integrally with the grip bar body 140, it rotates together with the grip bar body 140, and the sheave 150 rotates while being hung on the loop portion 350 of the upper rope 300.

[0059] Lower rope fixing parts 112 in the form of through-holes to which both end parts 415 of the lower rope 400 are fixed are formed on both sides of the center part 110. In an embodiment in which the grip bar body 140 is hollow, the lower rope fixing parts 112 penetrate from the outer circumferential surface of the center part 110 toward the hollow interior.

[0060] The first and second lower rope sections 410, 420 are introduced into the hollow interior of the grip bar 100 through the through-hole-shaped lower rope fixing section 112 and then pulled outward through the openings at both ends. After that, the ends of the first and second lower rope sections 410, 420 are tied together or fastened to a fixture and then pulled, completing the connection of the lower rope 400.

[0061] It should be reiterated that the scope of protection of the present invention is not limited by the description and expression of the embodiments explicitly described above, and that the scope of protection of the present invention is not limited by obvious modifications or substitutions in the technical field to which the present invention belongs.
